CZRUR52C6V8

Diodes - Zener - Single

CZRUR52C6V8 is a single Zener diode, also known as a Zener regulator. It is a two-electrode device, composed of a PN Junction. The diode can be used as both a rectifier diode and a voltage regulator.

Application Field

Zener diodes, including CZRUR52C6V8, are typically used as voltage-regulating components. They are often included in voltage-regulating circuits in order to provide a reference voltage. These circuits can be found in a wide range of electronics and electrical applications ranging from hand-held devices, to industrial and medical equipment, automobiles, and household appliances.

Zener diodes are also used in analog-digital converters and logic gates. In these applications, the diode is used to create a threshold for electrical signals. Zener diodes are also used in the test and measurement field, specifically in voltage-reference circuits.

Working Principle

A Zener diode is a standard PN Junction diode that is designed to effectively operate in the reverse-biased direction. When the diode is electrically reverse-biased, the diode becomes inhomogeneous and the potential barrier near the PN junction decreases. This causes valence electrons to get emitted, allowing more to pass through the barrier.

As current passes through the diode, it creates a voltage drop across the device, allowing it to remain in a steady state. This stable voltage drop is known as the Zener voltage. It is highly dependent on the semiconductor material used in the diode and can range from 5.1V to 200V.

In its normal operating mode, CZRUR52C6V8 is only used as a shunt regulator. This means that it must be connected in parallel with the current source. This is also referred to as a "parallel connection". In this configuration, the CZRUR52C6V8 diode can regulate the output voltage of the current source. As the current through the diode increases, the voltage drop across the diode also increases, allowing it to maintain a steady output voltage.

The CZRUR52C6V8 diode can also be used as a series regulator. This means that it must be connected in series with the current source. This is also known as a "series connection". In this configuration, the CZRUR52C6V8 diode can regulate the current through the current source. As the voltage across the diode increases, the current through the diode decreases, allowing it to maintain a steady output current.

CZRUR52C6V8 can also be used as a voltage-clamping device. In this configuration, the diode is connected in parallel with the power source and a reverse-biased diode to prevent overvoltage. This configuration is commonly used in AC-DC power supplies.
